PURPOSE:To reduce the compression work amount of a piston at its starting time and enhance the rate of gasification of the injected fuel by decreasing the suction air amount, when the engine is starting, idling or at a low temperature, and by increasing the feed-back amount of the exhaust gas. CONSTITUTION:A normally open contact 19 is in on at the time of starting from low temperature, and if a switch 20 is turned on by turning on the ignition switch 22 and also the starter switch, actuators 29, 31 are fed with current immediately from a battery 24 through point Q, so that an exhaust gas feedback valve 28 opens an exhaust gas feedback pipe 27 as well as a suction gas control valve 30 shuts a suction pipe 25 approximately. The ignition plug 6 is put in operation at the same time, to fire forcedly the fuel injected from the fuel injection valve 5. Now the engine is started. Even at the time of idling, the switch 23 is set on unless the accelerator pedal is stamped, so that the above-mentioned action is kept on. |
